Patented June 19, 19230 mm are ALFRED E. WIT'I'IG, OF ROCHESTER, YORK-ATTACHMENT FOR JARS.

Applieationfiled October 30, 1922. Serial No. 597,739.

To all whom it may cancer mi Be it known that I, ALFRED E. WITTIG, acitizen of the United States, and resident of Rochester, inthe county ofMonroe and 6 State of New York, have invented certain new and usefulImprovements in Attachments for Jars, of which the following is aspecification.

The present invention relates to an at- 1 tachment for jars, such asfruit jars of the type in which the cover or closure is provided with abail-receiving recess and two camming portions on opposite sides of therecess over which the bail is caused to pass to enter into the bailreceiving recess. An

object of this invention is to provide an attachment which willcooperate with these camming portions and the walls of the recess forthe purpose of causing the cover or closure to be held in tightcooperation with' the jar by the bail, after the la ter has becomeexpanded or stretched from use.

To these and other ends, the invention consists of certain parts andcombinations of parts, all of which will be hereinafter described: thenovel features being pointed out in the appended claims.

In the drawings: v Fig. 1 is a plan view of'a ar equipped with thepresent invention;

Fig. 2 is a fragmentary sectional view on the line 2--2, Fig. 1; .Fig. 3is a sectional view on the line 33, l F i 4 is a view of the under sideof the attac ment; and

Fig 5 is a perspective view of another embodiment of the invention. I

Referring more particularly to the drawings, 1 indicates the jar and 2the cover or closure which has its edge seated on a pack-.

ing 3 resting on a seat 4 at the upper end of the jar. This cover isheld in place by a swinging bail 5 of known construction plvotallyconnected at 6 to a swingmg member 7, which tends to draw the bail withpressure on the closure 2. The closure has on its top a pair of camportions 8 extending in opposite directions-from a notch or recess 10.

59 In operation the bail is forced upwardlyover one of the cams portionsto enter the notch or recess 10 after which swinging member 7 is swungdownwardly to place pressure on the bail, all of which form part of awell-known construction and is not claimed herein.

The clamping means forthe top 2 becomes in time so weak-or stretchedthat it will not place the properpressure upon the top and, in order toobtain this pressure, this attachment is provided. Two embodiments ofthis attachment ar illustrated, one in'Figs. 1 to 4 and the other inFig. 5A In the embodiment illustrated in Fig. 4, the attachment isformed from sheet metal to provide a circular substantially invertedcup-shaped portion 11, and two arms 12 extending from diametricallyopposite sides-of the -cup'-' shaped portion and downwardly withreference to the same. At or near the center of the attachment atransversely extending groove 13 is provided, in the top surface of thecircular-portion 11, and on the under side, of the attachment twolongitudinallyextending grooves 14 are provided, these grooves leadingfrom the transversely extending groove or recess to the ends of thearms. The grooves 14 receive the cam portions 8, while the projectionformed between th inner ends of the longitudinal grooves by depressingthe top surfacesof the attach the recess 10. It, will thus 'be seen thatthe arms of the attachment act' as cam surfaces for the bail andserve tohold the attachment against transverse movement'of the bevell-ingprojections of the cover or closure. The transversely extending recessor groove serves as a locking recess for the bail and the projectionformed on the. under side of the attachment beneath the transversely.extending groove serves to enter the recess be.- tween the cam portionson the cover to prevent the longitudinal movement of the attachment onthe cam portions of the cover.

, ment to provide the transverse groove lies in a In the embodimentshown in Fig. .5, the

parts are the same except that the-central portion is in the form of twolaterally. projecting arms 11, which take the. place of the invertedcup-shaped portion 11 of the embodiment shown in Figs. 1 to 4:. f

From the foregoing it will be seen that there has been providedanattachment for jars of the type described which will permit theobtaining of a stronger clamping action on the cover after the clampingbail has become weakened.

What I claim asm ..-invention and desire; to secure by Letters atent is:

1. A jar attachment 'comprisi'ng'a central portion provided with atransversely extendlng bail-receiving recess and two arms extending fromsaid central portion and having means for interlocking with the camportions of a jar closure.

2. A jar attachment comprising a central portion provided with atransversely extending hail-receiving recess, and means for interlockingwith the cam portions of a jar closure.

3. A jar attachment comprising a central v portion'provided with atransversely extend- I 4. A jar attachment comprising a central portionprovided with a transversely extend-' ing bail-receiving recess on oneside of the attachment, and two arms extending from said central portionand having each alongitudinally extending recess on the opposite side ofthe attachment, said central portion also having a projection on theunder side between the longitudinally extending recesses to enter thebail-receiving recess of the jar closure.
